Ya it has porterbuilt stage one setup front an rear, which is basically plates, cups an bags in place of the springs. He doesn't have air management yet so he can only air it out once. He has it setup with Shrader valves an then airs it back up with a portable 5 gal tank he fills with his home compressor before leaving.
Pretty much all I could do when I first bought the dually... So glad I got all my stuff hooked back up via the switches
